RHG'DE ISLAND, A CORPORATION OF RHQDE OPI-ITHALMIC MOUNTING.

Application filed December 12, 1522. Serial No. 66,51

This invention relates to improvements in the construction of ophthalnic mountings more particularly to that type of mounting known as Oxfords, and has for its object to provide nose-gripping members for mountings, which are formed each with a metal core having a non-metallic covering whereby these gripping members may be connected to a mounting and bent and adjusted to iit the nose of the individual wearer.

A further object of the invention is to form the core of the grip of wire and connect its ends to the lens rims.

The invention further consists in forming a loop in the wire intermediate the ends of the covering and that portion imbedded in the lens rims, to permit of wide adjustment in these grips to accommodate the mountings to the different wearers.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a rear view of the` mounting showing my improved form of grips attached thereto, one of the rims being partially sectioned to show the ends of the wire core as imbedded therein.

Figure 2 is a section on line 2 2 of Figure 1, looking in the direction of the arrow.

Figure 3 is a top edge view showing one of the lens rims in section and the nose grip as connected thereto.

Figure 4L- is an enlarged view of one of the nose-gripping members showing the wire core with its non-metallic casing in section.

It is found in the practical construction of ophthalmic mountings particularly those of the Oxford type, of advantage to construct the nose-gripping members with a metal core whereby they may be bent about and so readily adjusted to fit the nose of the wearer, and also to cover the metal portion of these gripping members with a non-metallic casing to prevent the acids of the skin from acting and oxidizing the metal; and the following is a detailed d-escription of one means by which these results may be accomplished With reference to the drawings, 10 designates the rims in which the lenses 11 are mounted, which rims may be formed wholly nected together' by a bridge member 12 into which may be set an elongated strip of spring material as at 13, see Figure 2, if desired.

It is found in practice in the construction of inountings of this character of advantage to provide nose-gripping members 14 which may be readily adjusted to considerable ei;- tent to t the noses of the different wearers, and in order to obtain this result I have provided acore, preferably of metal wire 15, which is covered with a tubing 16 of nonmetallic material. At the ends of this nonmetallic covering, I preferably bend the wire into loop or coil form as at 17 and then imbed the ends 18 of the wire as at 19 into their adjacent non-metallic rims.

By forming a loop or coil 17 at the ends of the covering, I am permitted considerable latitude in the adjustment of the nose grip, that is, I may stretch out or elongate either one or both of these loops to better adjust the grips and cause them to more accurately lit the noses of the different wearers.

In some cases, I may form this core of a resilient wire whereby the wire may exert a spring gripping tension on the nose grips, if desired.

I have shown and described the core of these nose gripping members as formed of wire but these members may be formed of metal in any desired shape and covered with a non-metallic material, but in other cases these metal members may be leftbare or uncovered, if desired, and the metal so connected to the different lens rims or other portions of a mounting as to be readily adj usted relatively thereto.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood, that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim: y

1. An ophthalmic mounting comprising a pair of non-metallic lens rims, a pair of nosegrippingf' members each. formed cf a wire bent into loop shape, n non-metallic covering thereoif'er, the Wire et the ends of the covering being bent into spring helical coil and the ends of the Wire being` attached to its adjacent rim.

2. An ophthalmic mounting comprising; n. pair of non-metallic lens rims connectedby a bridge member, nose grips each formed o1 a metal Wire core bent into substantially loop shape to form e noseengaging portion7 n non-metallic covering` for said nose portion, and both ends of said core being imbeddeo in its adjacent lens rim to connect the grip thereto.

3. An ophthalmic mounting' comprising pair of non-nietallie lens rims conn cted by a bridge member, nose O'rips each formed of a metallic Wire core in substantially loop shape, e non-metallic covering` therefor and portions of the core at the ends of the covering being` exposed and bent into coils and that portion beyond the coil being imbedded in the adjacent rim.

4. An ophthalmic mountingcomprisingl zi pair of nose gripping members7 each formed of a Wire core bent into substantially open loop form, a non-metallic covering therefor, the Wire at the ends of the covering;` being` bent into coil form, and the ends of the `wire being attached to the mounting.
